The Corinthia in Covent Garden is one of those places that generally lives up to all the hype. As soon as you enter the space you immediately understand why: the interiors are dark, it’s covered in Italian marble, and the vibe is moody but polished. The ESPA is one of the city’s largest with twenty-nine treatment rooms and even a stainless steel swimming pool. Along with a robust roster of treatments—signature facials and massages—there’s also a selection of customized treatments that focus on detox, sleep, pregnancy, and weight loss. The best part? Their day spa offerings include access to everything from the gym and thermal floor to the sauna and steam rooms and relaxation areas.
